About 3:45 p.m. Tuesday, a Kia Spectra and an Acura, both driving northbound, got into a fender-bender near the Lake Herman Road off-ramp in unincorporated Solano County, said California Highway Patrol Officer Rick Weaver.

The driver of the Acura honked and motioned for the Kia driver, Everett Wright, to get off the freeway to check for damage, Weaver said. But as both vehicles exited, the Kia drifted to the shoulder and hit the wall of a drainage canal before going airborne, Weaver said.

A fire crew from Benicia, arriving at the scene just minutes after the crash, found the driver and his two passengers unconscious. All three died at the scene, Weaver said.
